What steps are involved when upgrading cakephp from version 2.2 to 2.3? [closed]

Question

I want to upgrade my CakePHP app from version 2.2 to 2.3, what should I do?

Is overwriting the lib folder enough? I checked the diff and noticed there are also changes in the app folder, so its not clear if these needs to be updated as well.

Migration guide has no information on how to perform the upgrade.

Answer 1

Updating the lib folder for a "minor" upgrade like this is generally enough.
A complete list of changes/checks you can run when migrating is always available in the Migration Guide.
